Square footage is a measurement of area expressed in square feet. It represents the total surface area within the boundaries of a two-dimensional shape and is commonly used in construction, real estate, and interior design to quantify space.
Different geometric shapes require different formulas for area calculation:
Rectangle: Length × Width
Circle: π × Radius²
Triangle: (Base × Height) ÷ 2
Square: Side × Side
Ellipse: π × Semi-Major Axis × Semi-Minor Axis
Note: All measurements must be in the same units (feet for square footage).
Details: Accurate area calculation is essential for material estimation, cost calculation, space planning, and compliance with building regulations. It helps determine how much flooring, paint, or other materials are needed for a project.
Tips: Select the shape you want to calculate, enter the required dimensions in feet, and click calculate. Ensure all values are positive numbers for accurate results.
Q1: Why calculate square footage?
A: Square footage calculation helps in planning construction projects, determining material requirements, and calculating costs accurately.
Q2: How do I measure irregular shapes?
A: Break irregular shapes into regular geometric shapes, calculate each area separately, then sum them up.
Q3: What's the difference between area and perimeter?
A: Area measures the surface covered (square units), while perimeter measures the distance around the shape (linear units).
Q4: Can I use this calculator for metric units?
A: This calculator is designed for feet. For metric units, use meters and the result will be in square meters.
Q5: How accurate are these calculations?
A: The calculations are mathematically precise based on the formulas. Accuracy depends on the precision of your measurements.
